LEWISTON-CLARKSTON VALLEY, ID--A Lewiston-Clarkston couple created a documentary highlighting five unsolved murders from the late 1970's linked to one suspect.

The Lewiston-Clarkston Valley is a safe place to live, but in the late 1970s, people lived in fear of a serial killer.

Those unsettling years of the late 70's early 80's are seared into Vernon Lott's memory, five people murdered or missing, all within a few years. So together with his wife Jennifer Anderson the two sought out the victim's families to film a documentary.

Christina White was the first victim, then came a startling string of four more.

The archives of the local newspaper help shed light on the cold cases. As the news articles show, back then law enforcement often waited, sometimes days, to search for missing children.

One of the victims, 22-year-old Kristen David, vanished while riding her bike between Moscow and Lewiston. Vernon remembers hearing when her dismembered body was pulled from the river.

The other three victims are all tied to the Civic Theater in Lewiston; 21-year-old Kristina Nelson, her stepsister 18-year-old Brandi Miller and Former Air Force Cpl. Steven Pearsall who was 35. It's believed Steven may have walked in on an attack of Kristina and Brandi.

You might be surprised to learn, there's someone police say is strongly connected to at least four of the five murders. Lewiston police say former resident Lance Voss was seen at the theater and owned the home where the 12-year-old girl was last seen. He also drove the route taken by 22-year-old Kristen David who was last seen on her bike.

Voss declined an interview for the documentary and has never been charged.

Investigators say they lack the strong physical evidence they need to get a conviction. Part of the reason was two of the bodies were never found. That makes healing difficult for the families, law enforcement and people in the valley.

Lance Voss moved to the east coast in the late 90's.

Captain Tom Green of the Lewiston Police Department says these cases are in the back of every officer's mind. All of them would like to see them resolved, however, the case status is inactive at this point.
